66 Yellowboy Forearm

[2canes]

I have a new 66 yellowboy in 45 Colt,it shoots and cycles well. About the only problem is after a couple a dozen shots the forearm scoots forward about .060. Does anyone else have this problem and how can I fix it myself? I've called Uberti and the were No help.

The wood does contract over time, especially if it was "green" when shaped. Common occurance. .060 sounds familiar, (been there)
